In Japan October 26, 1934 1 Claim.

This invention relates to an apparatus for use in combination with asound reproducing device wherein a plurality of pictures or otherillustrations showing a story, poses of a dance, sceneries oradvertisement pictures may, successively and .at regular intervals, beshown to the public, as the explanation, speech or musical accompanimentcorresponding to the pictures is reproduced from the sound reproducingdevice.

For this purpose, the apparatus is provi-ded with a synchronizingmechanism, by means of which the rotary movement of the shaft of theturntable of a sound reproducing device such as gramophone and the likeis transmitted to a shaft on which is mounted a number of cardboardsdrawn, painted or printed with necessary pictures to be shown to theaudience, the cardboards being successively and at regular intervalsfreed from engagement with the supporter shaft .and disappear from sightby the rotary movement of the supported shaft i. e. as the shaft of theturntable rotates, thus synchronizing the picture show with the soundsreproduced from the record on the turntable.

The invention will now be more fully described with reference to thedrawing, in which,

Figs. l and 2 show vertical and horizontal sections of one embodiment ofthis invention,

Figs. 3 and 4, front elevations of the two types of cardboards cut withholes, of different shape, and

Figs. 5 and 6, side and front elevations of the end of the supportingshaft for cardboards Referring to Figs l and 2, the numeral I representsthe phonograph to which is attached the casing 2' of the apparatusaccording to this invention. On the upper part of the back wall of thecasing 2, a supporter shaft 3 is journaled, the front part of the shaft3 projecting into the casing 2. A locker pin 4 is pivotably mounted onthe front end of the shaft 3, as shown more clearly in Figs. 5 and 6.

The cardboards on which the pictures to be shown are drawn may bedivided into two groups.

,I The cardboards I6 of one group and those of the slit-s oftheperforations IB and I9 are at right angles to each other.

The supporterv shaft 3 carries a ring 5, slidably mounted thereon, and ahelical spring 6 wound on the said shaft 3 at the back of the ring 5,and adapted to press the said ring 5 against the back surface of thelast one of the cardboards I6 and I1 supported by the shaft 3. Y

The device for synchronizing the picture show with the sound will bedescribed hereunder. On the rear end of the shaft 3 projecting out ofthe casing 2 is formed a bevel gear 1, co-acting with another bevel gear8, secured to the upper end of the vertical shaftv 9 supported by thebrackets secured to the back wall of the casing 2. The shaft 9 carriesat its lower end a worm wheel I0, co-acting with a worm II formed on ashaft I2 journaled on a bracket secured to the back wall of the casing2. To the rear end of the shaft I2 one end of a flexible shaft I 4 isfastened, the other end I 5 of which is adapted to be connected with theshaft I3 of the turntable of the gramophone I, permitting the insertionof the upper end of the shaft I3 of the turntable, but prohibiting therotational movement thereof relative to the flexible shaft.

For mounting the cardboards on the shaft 3, the pin 4 is turned aboutits axis to the horizontal position as shown in dotted lines in Fig. 5,and then cardboards I6 and I'I are alternatingly mounted on the shaft 3by passing the pin 4 through the perforations I3 and I9 of thecardboards IB and I1 respectively. When the required number ofcardboards have been mounted on the shaft 3, the pin 4 is turned back tothe position shown in full lines in Figs. 5 and 6. The cardboardsmounted on the shaft 3, will be pressed forward by means of the spring 6acting on the ring 5, as hereinbefore stated, but will be retained inthe position by the pin 4, and the pictures on the foremost cardboardsI6 or I'I (as the case may be) may be viewed through the window 2| inthe front wall 20 of the casing 2.

When the rotational movement of the shaft I3 of the gramophonecommences, the movement will be imparted through the flexible shaft I4to the shaft Y I2, then through the worm II and the worm wheel I0 to theshaft 9, and thence to the shaft 3 by means of the bevel gears 8 and 'I.The rotary movement of the shaft 3 will cause the pin to revolve in avertical plane, while the cardboards remain stationary on the shaft.During the revolution of the pin 4, it will take such a position as tocoincide with the slit of the perforation I8 (or I9) of the foremostcardboard I B (or I1), so that the cardboard will no more be retained bythe pin 4. Then the cardboard will be pushed forward under the action ofthe spring 6, and will drop from off the shaft 3 by its own gravity, sothat the next cardboard will appear before the window 2|, but Will beretained on the shaft 3 on account of the pin 4v not being incoincidence with the slit of the perforation on the cardboard. By thefurther rotation of the shaft 3 by a quarter of a circle, the pin 4 willbe brought before the slit of the perforation I8 (or I9) of the secondcardboard I6 (or l1), and will fall down from off the shaft 3, by thereason as hereinbefore stated. Thus, by the rotational movement of theshaft 3, cardboards I6 and l1 are alternatinglyfreed from engagementwith the shaft 3 and disappear from sight at regular intervals (that is,four cardboards for each complete rotation of the shaft 3).

It will be easily understood that the interval at which each cardboard I6 (or I1) disappears from sight may be adjusted by changing the rate ofgearing down the speed of rotational movement of the shaft 3.

The apparatus may be used for amusement, advertising or educationalpurpose; the pictures on the cardboards may be of a story, poses ofdancing, sceneries or advertisement pictures, which may be successivelybrought before the window 2| and retained in the position for apredetermined period when the corresponding sounds such as theexplanatory speech on the story, scenery, or advertisement, or musicalaccompaniment is being reproduced from the record on the gramophone.

We declarev what we claim is:

In combination with a gramophone having a rotary turntable shaft; a carddischarging device comprising a supporting shaft, a series of cardsloosely mounted upon said supporting shaft, each of said cards having anopening extending in a direction ldifferent from that in which theopening of an adjacent card extends, a pin mounted upon one end of saidsupporting shaft and rotatable therewith, said pin fitting into theopening formed in any one of said cards in a predetermined position ofsaid supporting shaft, means pressing said cards toward said pin, andmeans connecting said supporting shaft with the turntable shaft of thegramophone and transmitting'the rotation ofthe latter to said supportingshaft, whereby due to the rotation of said pin, said cards are caused todrop one by one from said supporting shaft.
